xlua、tolua性能对比

　　Unity版本：2018.4.3,mac版

　　测试平台：都选择android平台, 编辑器下运行

　　xlua版本：2.1.14

　　tolua版本：Aug 9, 2019发布版本

　　测试方法：相同的lua代码，每个测试用例取稳定值

　　测试结果：

　　通过上图发现，xlua全面占优啊。附上测试的lua脚本:

if not UnityEngine.GameObject then
error("Click Make/All to generate lua wrap file")
end

local Vector3 = UnityEngine.Vector3
local GameObject = UnityEngine.GameObject
local Profiler = UnityEngine.Profiler
local Time = UnityEngine.Time

local Quaternion = UnityEngine.Quaternion
local SkinnedMeshRenderer = UnityEngine.SkinnedMeshRenderer

function main()
print(jit and "jit on" or "jit off, pls run test with luajit")
end

local cube = GameObject("Script cube")
local prefix = jit and "jit on" or "jit off"

function test1()
